Excel formula with if and vlookup ?

First of hello Community!

I am using :

Microsoft® Excel® for Microsoft 365 MSO (Version 2202 Build 16.0.14931.20272) 64-bit

I need VLOOKUP and IF formula with more conditions, maybe even some other formula:

I have two tables:

First table is with list of data of numbers.

Second Table where these numbers are grouped by same characteristics.

I need some kind of IF and VLOOKUP (or something else) to:

1. If only one ID with characteristic is in first table don't return data.

2. If only one ID with characteristic is repeating don't return data.

3. if there are two or more ID with same Characteristic, then return Characteristic in first table behind each ID.

thanks in advance!
